Jennifer Aniston appeared on last night's episode of Chelsea Lately, and the 43-year-old actress chatted with her BFF about nudity and drug scenes in her upcoming film, Wanderlust.

Jen admitted that there would be a lot of "slow motion, action nudity", but we're more curious about the part where she drops acid!

When asked how she prepped for the scene (Chelsea quipped, "I know I've tripped on LSD, so it wouldn't be a problem"), Jen said, "Yeah, I've actually never done LSD. So, I don't know. I just kind of imagined every greatest fear I could have. Which is like, which is what happens. And it was shot...was that kinda trippy?"
